- Fix some documentation issues
- Relax constraint on logstash-core-plugin-api to >= 1.60 <= 2.99
- Force encoding the gemspec of this plugin into utf-8 to make sure updating all the plugin works see elastic/logstash#5468
- Use oracle JDK8 for travis build
- Use new Event API defined in Logstash 5.x (backwards incompatible change)
- Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash
- New dependency requirements for logstash-core for the 5.0 release
- Plugins were updated to follow the new shutdown semantic, this mainly allows Logstash to instruct input plugins to terminate gracefully, instead of using Thread.raise on the plugins' threads. Ref: elastic/logstash#3895
- Dependency on logstash-core update to 2.0
- First version of the webhdfs plugin output
